1. Specific Frequency Band Compatibility：The GL - DY418 operates within the 824 - 960MHz frequency band. This makes it well - suited for devices that rely on this frequency range, such as certain mobile communication devices, radio systems, and some wireless sensors. It can effectively receive and transmit signals within this specific band, ensuring seamless communication for compatible equipment.

2. Decent Signal Gain：With a gain of 3 dBi, the antenna can boost the signal strength. Although it may not be as high - gain as some specialized antennas, it still provides a noticeable improvement in signal reception and transmission. This is beneficial for extending the range of wireless devices, especially in areas where the signal is weak or there is interference.

3. Standard Impedance and VSWR：Featuring a normal impedance of 50 ohms and a VSWR (Voltage Standing Wave Ratio) of ≤ 3, it ensures efficient power transfer. The 50 - ohm impedance is a common standard in the industry, making it compatible with a wide range of devices. The relatively low VSWR means less signal reflection, which leads to better overall antenna performance.

4. Vertical Polarization：The vertical polarization of the GL - DY418 is designed to align with the polarization of many base stations and wireless devices. This can help reduce interference and improve the signal - to - noise ratio, resulting in a more stable and reliable connection. It is particularly useful in urban environments where signal reflections and interference are common.

5. Compact and Durable Design：With a height of only 67 mm and a black rubber exterior, the antenna is compact and unobtrusive. The rubber material not only gives it a sleek appearance but also provides some level of protection against impacts and environmental factors. It can withstand a temperature range of - 30°C to 60°C and humidity levels from 5% to 95%, making it suitable for various indoor and outdoor applications.

Application scenarios

• Industrial wireless sensors and IoT networks.

• Vehicle-mounted communication systems (e.g., fleet tracking).

• Outdoor remote monitoring equipment (e.g., weather stations).

• Telecommunication base stations in harsh environments.

• Portable devices requiring stable signal transmission.
